This is a warning more than a suggestion, and is kind of logical really, but I was just writing up a showcase post (on my sword, Jonathan!) and was doing it directly into the 'post topic' form, but as I followed up some fresh research online I was logged in for quite a while. By the time I came to submit the topic for publication, I'd been logged out (timed out, I guess) and I lost the post! Often I can use my back button and the field still contains the text, but not this time - all gone.
So, my advice (you probably all know this
) is to write long posts in a text editor first, and then copy and paste them in when you're ready to post, then you can add in any BBCode and links you require etc. I quite often do that, actually, but not this time
I haven't got time to re-do it now, but the sword will still be next on my list - promise!
