Do not ever tap squidport entrance with floating tile when visiting friends!!

Yes, seems a good call here. I just tried this on a neighbour's town and I'm assuming they get 1 tile added to their inventory. I did this as one of my tasks, exited to Friends overview, came back in and was able to do the same thing again. With my third task, again, repeated.

So I'm guessing that when he logs in next he'll have 3 tiles ready to place. I hate to turn this into an add me thread but if anyone fancies doing this as an exchange on a daily basis for a few weeks until the tiles are uncovered, that would be helpful all round.
