Oh please dont do away with the for sale thread. I haven't read the whole thread so forgive me if this has been said already but....
I hope you will all agree I am a very regular Mumsnetter with a lot to contribute (though I am not into handing out tips of the day, I admit) and I would seriously miss the for sale board. I rely on it to make a few pennies for my children's endless need for new clothes, and also occasionally buy things from other Mumsnetters. However, they are only a few pennies and having to pay to advertise would mean I would not use the for sale board anymore. I also use charity shops and nearly new sales so I would not be entirely bereft without it, but it would be sorely missed.
I do think it is a good service and intrinsic to the support we mothers can give each other if we can buy and sell our second hand goods here. Not everyone here is well off and making ends meet as a parent does seem to be a common theme across all the subjects discussed here, not just in buying and selling.
I do agree, however, that the system is open to abuse from outsiders and so I would propose that MN Towers should introduce a way of keeping out those who are only using MN for the free selling board. Perhaps you should have to rack up a number of posts first, or you should be a regular member for 6 months or so? Is that possible?
I also would not object to the for sale thread being shown somewhere other than on talk. I know people can click on "without buying/selling" but maybe that is not enough. I admit I sometimes find all the sales threads cluttering up the chat irritating, but I am not in the habit of clicking "without buying/selling" because I like to look out for a bargain.
