I respond when I feel I can contribute (I know absolutely nothing about SL, SL rehab, etc so my advice would be less than worthless).
I am good with CAs and being tenacious (i can usually find a way to leverage), okay with auto loans, better with mortgages, and real good at buying/selling a home, I understand SOL and lawsuit and contracts. There are days I am very busy and visit the forum, scan the titles and see if there is something I can add that is worthwhile (and hasn't already been said). Other days I can respond all day long or wait for answers to questions I posed to then respond because I am online working and just keep a second window open and check it occassionaly
Truthfully, we are here voluntarily (it's not our job) and we are here because of what we have learned in our lives that maybe could help someone else - which considering the price that people pay for the free advice here (and encouragement and support) is very altruistic of everyone.
And when a post is made does matter -- just bump it so it goes to the top again.
