Sorry to butt in, but didn't really want to put it elsewhere.
The lurkers, I don't mind, indeed there is something to be said for having a good lurk, getting a feel for the site, understanding the wide range of topics and opinions that abound. A bit of time spent having a thorough lurk could be time well spent, so that an informed decision may be made before joining and making a contribution to the many faceted world of Gransnet. In fact, I positively urge you to lurk.
However the jumpers, I am not so keen on, especially when there is a distinct whiff of merde de vache about them, if you will pardon my French. I wonder what they hope to achieve, and having wondered, I am none the wiser, which vexes me somewhat, and I do not like to be vexed. Another point that is causing me a small amount of consternation, is the number of jumpers that we have had recently, again, I wonder why, and again, having wondered, I do not know.
So, in conclusion, I would say to things, namely, lurkers, feel free to lurk and if after a suitable period of time you would like to join us, then do so. Tell us a bit about yourselves, how you came to be here and what you would like to give to, and take from your membership. And to the jumpers, I say *F&#k O$$.
