@davisagli I think this is ready for merge, I think just it needs some rebasing.. this "revert revert" is not that cool...

[davisagli]

Thanks @bosim. I should be able to look at it soon.

[garbas]

should we use plone.api when we can? like sending emails? what is the policy on this?

[garbas]

this plip also introduces plone.schema as new dependency of Plone. need to look at status of it

[davisagli]

plone.schema is fine to include; it's also a dependency of the editable memberdata schema PLIP. At this point it adds an Email field.

[garbas]

i guess we also dont have plone.api plip there so there we go. code looks good i'll run tests and if pass locally i'll merge it

[garbas]

rebased on master and merged manually

[bosim]

@garbas thanks for reviewing and merging. :)
