Looking at the number of post you have, you are probably better off getting 4 shares which puts you at 5 giving a weekly 98% upvote instead of getting to 6 giving a 17% daily upvote. The value of unused votes are always destributed to active shareholders.
Anyway, it's up to you. I already changed your weekly upvote % to 98% assuming 4 more (4x4.7 = 18.8 Hive) If you do want to switch to daily upvotes and get 5 just send the (5x4.7 = 23.5 Hive) and I will adjust your upvotes. No need to use the "i agree to the terms" in memo. That is mostly there for now people that get in so they are more likely to do a bit of reading into everything.
Cheers,
