Thanks. It seems ( although I am unfamiliar with it TBH ) that threads will only appear in My FlyerTalk if I actually subscribe to them. The previous threads that I had posted in automatically appeared under a single drop down called My Threads and I had only to post to them for them to appear ( ie not to take the extra step of subscribing).

The other advantage was that if there was recent activity in a thread it came to the top of the My Threads list, whereas on the subscribed threads I have I have never noticed that.

I can certainly subscribe to threads going forwards but it has just added an extra step, and reduced ease of use from my narrow perspective. I understand there were probably good reasons to do so and that when I get used to the process it may be just as easy but so far it is anything but. IMHO at least.
