So you want to look at other carpet cleaners while you discus pre sprays and post cards??
IMO, here is what each forum has to offer.
ICS- free access to the one room where you can ask a question and have either a self professed guru or an actual professional guru or a guy with 3 weeks of experience answer it. Be very careful of the advice given as no one is held accountable for misinformation and the wolves are encouraged to hunt there. Very unmoderated unless you speak ill of one of the few advertisers left there. Very slow as of late. Inconsistencies in over mandated rules have chased most away.
Clean Fax- Even slower. Jeff Cross does his best to bring up interesting subjects but only five or six are listening. No funny business allowed.
T-M-F.- Rob Allens' supply shop sales cart disguised as an open forum. Lots of heavy moderation to protect the advertisers and Rob's interests. Also an outlet for Tre to sell you web site design which he is actually good at. Hucksters who cant get away with thier snake oil sales on other boards are encouraged to particapate. Reeks of Billy Grahmness. Lots of hip but unused features.
Billy's Board- See Clean Fax
Rickys Board- One topic allowed. Good if you're just getting into scrub and run.
Blue Board- Seven Rush Limbaugh impersonators.
Procleaners- Not a BB but a live room of guys telling war stories on most nights. Blatant infomercials on the others. For the dyslexic crowd. Bring your check book and your mute button for when ever Grif speaks.
Mikey's- A large gang of tough guys having fun, helping each other out while insulting each others looks and choice in underwear. Most humans that you would actually want to spend time with in person prefer this board for it's realness. Leave your tender feelings at the door.
Rug Hub- Great source of rug cleaning info. Get in and get out.
DirtyGrout-Great source of hard surface cleaning info. Get in and get out.
Something for every one.
