I don't know if these are possible, but it would be nice if:
Þ The thread titles could be in bold if we have commented in that thread. It would be easier to scroll through and quickly see the ones that I am most interested in.
Þ There was a way to search for PMs. So, for example if someone PMed me with question, and I weeks later I discover the answer but forgot who asked, I can just do a search for a keyword and find it. (I get a LOT of PMs)
There are two types of people in this world: Those who can extrapolate from incomplete data.
Speaking of PM's, I wish it would (or could be set to) default to always save a copy of your sent messages. My email program does that automatically, but the PM system here doesn't unless you manually check a box. I hate when i send a message and forget to check the box and then I don't remember what i said, and can't re-read it and see a typo to do a followup message to correct. The only way to get it back is if the recipient replies and leaves the original message attached.
Good ideas! I've been thinking lately about fixing the PM system to be nicer. I also have some ideas for making it easier to find the threads you are most interested in. Hopefully I'll implement some of them soon. Your feedback is helpful!!
