| Description: | There are a lot of monks that play Starcraft (including me), but often times we have difficulty finding people to play with. So, to organize us, I decided to write up a quick ladder. For those of you who don't know what a ladder is (or don't know what a real ladder is, unlike that pathetic bnet one), it is basically a league where one can only advance by playing higher ranked players. In the gaming community, everyone wants a ladder. However, once a ladder is up, the ladder admin(the guy who wrote it) becomes preoccupied with other things. Without someone to maintain the ladder, it soon dies. Therefore, I wrote a ladder would be easy to setup and maintain by the non-programmer. It is EXTREMELY easy to install; it uses 2 flat text databases (for easy cross-platform support), and was designed to be inserted into pre-existing designs via ssi so the ladder maintainer doesnt have to drudge through a buncha code. All the maintainer has to do is upload the scripts and set permissions, and its ready to go. I would really like to host this somewhere, if anyone knows somewhere I could do it, it would be really great. It wouldn't eat up much bandwidth or disk space, and I think that it would be one more thing that would enrich our community even more :) Update |
