Did try out the demo and tought that also the avatars of jomsocial was used in the chatbox, but it didn't. It has no connection with jomsocial at all :(
Even there are more small own avatar, if I login as admin my avatar of this extension is still user :(
They layout it is great, but for now I don't use it because I can't see jomsocial avatars or even if I login as admin the admin.png :(
When they fix that and also the abbility to use jomsocial avatars, maybe I even think about it to buy it again, but for now it was a waist of money :(
Easy to figure out how it works and easy to adjust at you own needs.
Also the developer is very helpfull if something is not working as was planned.
Even bugs that are found and mentioned are solved in a very short time with a update.
Keep up the good work!
Thank you for your feedback.
