It isn't exactly compulsory but I'd deem it a real favour if members could sign in when visiting the site.
That way when I see (like now) one member (me!) and 8 guests I'll have a clearer idea whether we have loads of people visiting who haven't joined, a number of search engine bots crawling the site (doesn't happen often enough, but it is happening more and more now), or simply members who haven't signed in.
Sub-topic: do members want me to incease the life of their sign-in cookies? These are the little files TMC writes to your computer so that the web server knows you're logged in. The default life of these is about a week, but at least one member has asked me to increase this lifetime as he signs in from a number of different computers and has trouble remembering his password!
Let me know if you have any strong views on this matter one way or another.
Thanks for listening
Phil
