Nothing was lost when we moved to this forum as far as I know, some picture links did go but most were fixed. I've spotted one or two since when trawling the old old pages. Nothing compared to that online picture linking site that killed all the pictures off. Glad when can now easily put them on here.
If you can't find it, post up and someone may be able to find it.. Sometimes I have had to trawl though, mainly as titles never seem to describe the threads.
Use the advanced search on your own posts seems to be the better way even if it's finikity
