Welcome to our forum.
I agree, poolforum.com is a good site. I have had no problem getting in. Beware, the posters over there have strong opinions on "Ben's" way of doing things.
I would also like to find a good pool forum. I have decided to extend my paver patio to make room for an above ground pool to accompany my tub and am as clueless about pools as I was about hot tubs before I got skooled here.
