i have a community website and i need to select a chat software widget / app. Unfortunatly i tested various software and till now idid not find the muist suitable solution for my n eeds.
I saw around there are many co,m,ercial app, opensource app and so on.
I need a developer expert on chat that worked already with chat system to evaluate the most suitable solution for my needs.
The issue is that the community is heavy loaded so most simple solution based on mysql / ajax in my opinion will risk to opverload the server that is already very busy.
