harrrrrry I don't remember ever having a minimum character count on giffgaff, though I've seen it on other forums.
No, we never have had a minimum character count on giffgaff but it has come up as a suggestion as being one way to cut down on the quantity of pointless posts a few times before.
I too have seen it elsewhere and it does make a real difference.
I'd be all for it; say minimum 250 characters, but like other suggestions on the same lines, it's never going to happen.
Despite saying that it's quality that counts, all I can think is that what giffgaff really want on the community is just quantity irrespective of quality!
