Prior to moving to Izmir, I did some googling, and didn't find much. And what I did find was in Turkish, which I do not understand.
When we actually moved here, we found that on top of the language barrier and notwithstanding the wonderful Turkish hospitality, Izmir is not really geared to welcoming foreigners, as a capital city would be for instance. This makes it more difficult to integrate at first.
Also, Mymerhaba "a community portal to make you feel at home in Turkey" does wonders for Istanbul and Ankara, but is not very helpful for Izmir.
Finally, although there are various web-connected groups of expats in Izmir, you have to know they exist to find them. The advantage of a Blog is that it is just as interactive as a forum with the added features of photos, links, and accessibility.
So there you go. Basically, I'm trying to find my way here and I thought it might as well be useful to others!
