I'm one of four administrators of CKMGaming, a fairly popular server that is looking to expand its resources while improving upon our approach to gameplay. We are looking into RP plugins such as Heroes, and are looking for a developer to write some custom code for Donator skills/characters and some other coding that we have been unable to find a good plugin for.
This would be a place for the dev to try out ideas and get direct feedback from administrators on what plugins we feel would be popular if developed. This would give the dev a live server to finish testing on and get feedback from players on.
If anyone is interested, or would like more details, please create an account on ckmgaming.net and send me a PM.
