Thank you @aggroed for explaining it. The fee was something I ask around the last few days and nobody has an idea about it "how it works".
How can i "track" the fee for now? Do I see an increase in shares?
For example, I have 1000 shares in a pool and after some trading in the pool, I see 1000,1 shares, depending on volume?
Would be really cool if you could answer it in some words, so i hammer it under my post with the question, so anyone that search for it, get the info :)
