What we should do is either allow anyone to revote (hard to do), let people PM a mod and ask them to (time consumoing), or start another one each month, identical to the last except in the time that it was created and then everyone can vote on that blank poll.
I could probably code up a PHP page using MySQL to keep track of sizes. If I get some spare time this weekend, I'll try to code something together and test it locally.
What kind of fields would people like?
I think it'd be good to have starting stats, and current stats, perhaps with the ability to just keep stats as you go along (similar to the one on Thunder's).
I think it should keep track of BPenis EnlargementL, NBEPL, FSL, EG, and perhaps erect width. Also, I could have it calculate erect volume based on the girth and length (like the penis volume calculator I wrote). And I can probably have it display the results and allow output in the desired units (that'd take locality into account). For instance, if you're from the US, you probably want everyone's stats shown in inches/cubic inches, whereas if you're from another country, maybe you'd want the units in centimeters/cubic centimeters.
It'd require a username and password to use, so you can update your settings and make any modifications. The locale preference would probably be stored in a cookie. Well, we'll see how it goes and I'll keep everyone updated.
