You have earned 21 merits, meaning you have just around 10 smerits to send, i consider that too small to start a merit giveaway thread,
except of course if you are looking for more merits from this thread, merit giveaways make sense when they are run by merit sources who have their source merit replenished after 30 days, that way they can give out more smerits and keep the thread active for a pretty long time. So i would advise you look for posts that meet your merit criteria and give merits to them without starting a thread for that.
2. No newbie account is allowed unless you feel your post or topic really deserve merit.
Why wouldn't you consider sending merits to newbies, if many users have likewise mindset then you prolly might not have earned any yourself.
