Hi, im new in using a desktops wallets, and i choose an a Electrum.
I don't understand almost anything about fees,blocks(i think it's called blocks) etc..
And playing with that i changed something.. today i sent 3 transactions, and they are marked with "low fee" with 0 transaction confirmations :/

I really like a electrum, but i don't understand how to set up fees properly..
Ca somebody help me please?
