Hi, I run a RP server and so for a while I used HeroChat so people can talk OOC in global and IC in local. However HeroChat has not been updated and I see an opportunity for a successful plugin. I'm not suggesting a complete copy of HeroChat just a simple chat plugin. It would have prefixes, suffixes and chat colour. Then as an alternative you can add different channels. I am not very knowledgeable about plugins so I don't know how lightweight this could actually be. If anyone reads this and think they can do it then please let me know. I am willing to pay some money towards the creation of the plugin as well. Thanks for reading.
iChat does the prefix + suffix + color, and is easy to use. It does not, however, have different channels.
