Vêndula of italki has just written some, polite, good English in her "Learning English" note illustrating "...for helping...". She wrote "So thanks (to) existing italki (users) for helping me so much." An example of "to help": "Why not use that stone to help open your coconut?"

Thanks :)

To help is a verb phrase and explains a purpose. Helping is a gerund in this case and explains the purpose of a thing and how it gets used. OK: Tammy updated her resume to find a better job.
