For those of you with Skype facilities (and it will be a growing number of you over the not too distant future !) you can now put your Skype id in your board profile in the same way as for your email address, website name, Yahoo id, etc., etc.
So for those of you who have gone to the trouble of setting up your sig blocks, you can now remove that nasty bit of gobble-de-gook and update your msg board profile (use the 'Control Panel' link at the top of the screen)
