What is all this with episodes and sessions an explanation

A bit of background

When I started this blog I had rather limited ambitions for it and was only really going to use it to host pictures of maps for my write ups on the Big bang burger bar, the local Burton and district Gaming Forum. Because of this I did not post the Session write ups on the blog right away and when I did post them I did so as one chunk, a single post covering the first six games sessions and the two Preludes which I ran for late comers to the main game. 

At that time Blogger rather chugged at this given tat the post was 20-30k words and I lost a lot of formatting and generally found the layout could have been done better so I split the post into three Episodes and these became episodes one through three, each of two actual games sessions, however with non  gamed interludes for characters whose players had wandered off and preludes for late starters even this was no the final case though after that I posted one Episode per game session I did not reconcile the two numbering systems. I have done now and you can see the result below - sessions in red are at the time of posting this  yet to happen.

The bold Roman numerals refer to the main game session, I committed the word session on every  for brevity as I did not think it made things clearer

I hope that makes more sense now
