Current version set amount of chat messages between 5 and 150. Any way to increase this?

that is set in the file acp\ajaxchat_module.php lines 91-94 depending on which setting you want to increase.

is there a way to increase size of chat window

you will have to edit the .shouts and .whois elements in ajax_chat.css and adjust the height: setting to the same on both elements

page header is "CHAT CENTER" any way to change that

that is in the language file ajax_chat.php on line 62, change it to what you prefer

Forum is phpbb3.2.2. forum and Ajax Chat for phpbb 3.1.
Applied changes I wanted according instructions and purged cache. Everything worked, no problem.
Thanks for help!
