Still online, we are. The code for this website is getting old, but still works well as far as I've seen. I may update it with new code and new features eventually, one day when I have both free time and focus. Until then, the content is still useful, I'm keeping it online. Comments and donations are welcome, but include your email address if you want a reply.

Ideas for the future of the site -
Here are some ideas I've been brainstorming. I don't think to much of the site should change, because it has been successful all these years with very little change. still nearly 1000 visitors a day to the site!
  • donations - I think it might be time to make some changes to the donations. I would rather see people get a lifetime membership and not have to worry about an expire date. here's an idea, a smaller recurring payment monthly, or 4 times a year, then maybe offer a second option, donate enough to cover the cost of the server for one month and you'll get a lifetime membership that never expires.
  • automated account creation - the membership process should be automated. I rarely hear a complaint about anything, but I don't think people feel so safe emailing me a username and password to set up an account. I think people may feel more safe dealing with an automated system. make a donation, then type your account into right in to the computer and have it set up on the spot.
  • members only forum - the site doesn't seem to need a full forum, but it could still benefit from a single simple board or mailing list, maybe. still optional, but maybe only available to members. non-members wouldn't be able to post on or see the forum. for those who donate to openly communicate.
You can send me your comments in the form above. I'm not putting any work into these changes without getting feedback from you!
If we have any web developers out there, we'd love your help! come on, my birthday's tomorrow!

Better forum? -
We are currently using vbulletin, but maybe there's a simpler alternative that would better fit the site. What do you think of this one? Please let us know what you think, keep vBulletin, or switch to SEO. Comment box is below.

ideas or comments?
please send us your comments or suggestions or any ideas you might have for the site. this is the easiest way for you to let us know what you think. just type in the box above and send.

Thank you, everyone who has helped support the site over the years. you've done your part, now help me do my part to improve the site with your input.

tips to download -
right click on the file you want and save target as/save link as. this will help prevent the system from double counting the bandwidth.
The bandwidth reset time is now set to 20 hours instead of a week. We hope this helps you get what you need without causing any problems with the site.

new server -
this week, we've moved the website to a bigger faster server. we have doubled the weekly download limit to 20mb and are now allowing hot-linking, so more people can get the documents they're looking for. this new server is still relatively low cost, but is a bit more to pay for each month then the last server. we still need your donations to help with this. thank you all who have supported the site and community!!!

upload files - If you have files you'd like to add to the site, we'd love to add them. Please don't upload anything illegal, harmful, or copyrighted. We will do our best to screen the files and put them online.
