Do you know what they were at least? If you can remember but can't find them I can throw them in.
After that I'll put out the test version - just did a live chat with 3 people and it worked with them all.
I mainly did some things that intercepted a request for an image and redirected it to a image hosted on dropbox, allowing me to log ip's
my best change was making the timeout time 1000ms instead of 10000ms
it boosted webserver performance by, well, 1000%
(I do hope I did that math right)
