I like your new sig. It looks pretty exotic! What language is it in, and what does it mean?

I like it too, but it is too long.

It's in "old" Caísa (my conlang) and I can't remember what it's meant to meen. I can't understand it either partly because I squashed all the words together. I think it's meant to say: Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch, in places it fits, howerver I can't find the word Tysilio in there. Perhaps someone else can spot it?
It's all written in an old fasioned style of spelling, which I quite like (although it's fairly impractical)
