Allow parent to specify "other file types" they wish to allow instead/in addition to the "catch-all" checkbox.
Instead of the catch-all checkbox to allow "all other file types", allow parent to pick/choose via a text box entry (maybe "separated by commas" ?) what file types they are looking to allow that are not listed. For example, I use an app called Spellboard by palasoftware.com and I can email the kids their spelling lists, but it's a proprietary file type with extension. sbq. Currently I cannot do this through their Kmail accounts. I'm sure there are other reasons to enable such a feature. Granular control is very desirable.
Thank you for the suggestion. Right now we do not have any plans to change this, so you will have to just select to allow all attachments. If we decide to change this, we will let you know but for now we will not be making this change.
I should clarify... I can't currently email this file type to them because I do not desire to allow ALL file types to come through. This is to protect our machines as much as to protect them. Thanks for your consideration!
