I don't think the parents need to have access to our files. I think sometimes they forget that we are normal people too off hours and we can sometimes go and have some beers, or have a good time doing other things. Yes, we have kids and run a day home but that's not our complete life.
I have set up a group on my fb page where I can add pictures or communicate with parents. The thing is I haven't told any parents about it yet ..lol. I almost don't want the affiliation that much that I'm thinking of just setting up my own blog page to show parents what we do sometimes.
