You say this can cause problems if multiple user request a change. (FYI before getting to your main point here, my PHP 'locks' the .js file while editing, so other requests can't interrupt.) Is that really different than multiple users requesting the same php page which must generate user-specific display? Or are you saying that external file-writing requires more processing time, and so creates a back-log with many requests?
I'll look into generating user-specific external files; can you give me a heads-up as to the php functions for this? Otherwise, I'll post in the PHP forum if I can't find it myself.
Thanks for your help.
