I've just come back to skritter after a long break and got tons of reviews. I heard from a friend that even if you cancel your subscription you can still do the reviews you have left. Is this true?. I have a feeling this will take a long time for me so it might be slightly more economical :P. then when I'm back on track I can resume the payment. Thanks!

That is correct. As far as I understand it you can do everything except add new words.

joshwhitson13 is exactly correct. We hold onto your information indefinitely.

@Scott I've got a question. Josh mentioned that you can't add new items in his comment above. I recently cancelled my account to basically do the same thing that Vigator wants to do, which is spend some time only reviewing previously learned stuff. Once I reactivate my account, and want to add a bunch of new items, do I only have to study each item once with tracking on, in order for that item to forever be a part of my review queue ?

So, in other words, after I reactivate my account and make a list of all of the words that I've been saving up while my account has been inactive, do I only need to go through that list once in order for all of the words/characters within that list to be added into my review queue's circulation forever ? And will it make a difference if the item is marked right or wrong ?

That's correct, Bohan. Skritter only stops you from adding words to your studies for the first time. So you can pay for a month, add a list from start to finish, and then cancel your subscription as you continue to learn the list.
