I agree with admin, I still use the search on here when I want to find out about a product . Chances are what ever I want to use or try out has already been discussed in 2004.
I think what puts some carpet cleaners off who have been around the block a few times is people coming on here asking all the same old questions eg. Whats machine do i need? whats the best prespray? etc .... etc.... Its not new ones fault because they are all the questions you ask when you start out, but answering it for the 5000th time gets a bit boring. Facebook has created closed groups which have cut this down a bit on some, but increased it even more on others. The problem with facebook groups is there is so many of them it could be a full time job keeping up with it all... and to be fair all thats the same old rubbish.
This forum is a good tool, Its got years worth of knowledge stored here for anyone willing to look and there are still enough experienced people using it to eventually get a useful answer to a reasonable question.
