Need some help staking. I bought ~735 TES and synced up the newest wallet over a week ago. Still nothing. I eventually locked the wallet and then unlocked for "mining". Still nothing. I would like to buy much more, but want to make sure it's all working before I get too deep into this coin. Any thoughts?

[EDIT] I have let the wallet run for several days at a time. Do I need more coins to stake?
just wait - patience is needed here.
wallet is synced ,fine, keep it unlocked and it will do its business. I imagine it would take at least a week with the relative size of
stake.
735 coins out of a total 73.9 million total so far, is a relatively small stake but it will eventually be staked if the wallet is left open.
buy more by all means.
