Well you don't need to write refer name any where admin can see it and he will give 250 000 to you and 500 000 for referral person under who you have joined and as lemon said you need to create thread in Information Section as "Drowned Bonus" and put your profile link where you have add those signature link and you don;t need to update or tell admin admin give points on every first week of every month !
and if you add any new forum in list then add your profile link and as on date post count !
No, it is compulsory to put the referrer name in the bonuses thread, as dada has made a new announcement in the "information board" last month. Sorry, now I"m too lazy to dug that thread. If you want, you can search the thread in the "information board" section. He has clearly written that in order to get referral bonuses you have to write in the first post of bonus thread your referrer name.
