In your Wallet within Steem Engine, if you look across each token, to the right, there is a padlock icon - hover over it it says Stake Token. Just click that and process the transaction with your active key (or keychain). The token should be staked within a few seconds.
I've made unstaking very painless - it takes just 2 days and done in 1 transaction. Staking is not, for MAPX, designed as a lock-in but rather to distinguish between holders who just wish to trade tokens and those who want the benefits such as upvotes and freebies.
Once done, I will add you to the voting bot.
