Dear Admin,
   I’ve suggestion for this website how we can make this website active. Last night I came up with this idea while I was working on my homework assignment and now I’m going to reveal this secret to you guys. As you know all members when they register with this website they always put their birthdates’ too to register on this website. Well some of the members they may not put their birth date because they doesn’t like it but let’s assume website admin has all the members birth date on their list; so my peak is that website can start sending greetings to their site members so this way it will be a good reminder for them that this website is still exist and we’ve always been remember and you’re very valuable member and a part of this community. Hope you like my idea if you doesn’t like it sorry I tried but this is just the brain storming ideas obviously you guys are seniors and you can improved than what I propose. If I’ve make any mistakes please correct me. Alright let me come to an end with this quote:
