Well, I did purchased FlashChat and spend an entire afternoon installing it and trying to figure out how the heck it works. Here are my findings:
1. The installation instructions are garbage. If you want to try it out (and throw 5$ out of the window), do not follow what the readme.txt files say. Go directly to the integration directory and read the file that pertains to the vBulletin. It will save you the headache. Also, be prepared to alter the permissions of several files, but not in the way the instructions suggest. In order to install this POS, you have to set several files to 777 permission, otherwise their install script fails.
2. Flashy it is, usable it is not. I spend an entire afternoon trying to customize a few things here and there. No way. It doesn't even understand $vboptions variables. The worst thing I faced was the user interface, of the area where the messages are displayed.
Have a look at the picture below:
If you can separate who wrote the message, at what time, and what the message is, from this screen, then you are much better than I am. So I posted a request in the support site, asking for some help on how to put this in columns. One column for the time and user name, and another one for the message. Well, their first answer was that I can't change it because it is in Flash. So I said fine, tell me in which file I have to work to make the change I want. And the answer to that is "Sorry but you have to find out how to do this yourself. This Forum is not supporting you in your changes of FlashChat code".
Now I know that 5$ is nothing, but this is a matter of principle. These people proclaim that they have support, and that they give away the source code with the purchase. I didn't ask them to write any code for me, all I asked is where I should go in and change the code, I do not want to spend my time looking around. Nope, that's not available.
I do not know about you guys, but I am still in the look-out for a Chat system. That crap is out of my site.
