History of EEE0910 Association

Hi..

This's Benhur.B a B.E(EEE) student from DMICE (Chennai) batch (2009-2013).

Now I give you a brief explanation of the History of Our EEE0910 Association.

"When We entered into our EEE department after completing our 1st year(in 1st year all're common, so no department)some of my classmates regularly used to text (sms) and ask me about the subject and assignments to be finished on each day. Suddenly I got an idea that if we suppose send the sms by a whole group , it'll be helpful to our class and will lead our class into a responsible one (this only the turning point to start the association). So I consulted with my hostel friends and asked their suggestion. As soon as hearing this, they appreciated and gave their full support. In 1st step I send a msg as starting of association and whoever willing to join just sms as "JOIN EEE0910 " To my mobile. Quickly most of the friends joined in our association {association established date 28/8/'10}. I started my service of forwarding "REMINDERS" to all and also started many useful services like Sending important Questions,Exam timetables, and so on. Now our association has spread its tentacles  in most of the Social Networks."

In facebook - EEE0910 (group)
Orkut - E3beasts
YAHOO - dmieee0910@yahoogroups.co.in
Google : http://dmieee0910.blogspot.in
and so on.

One of the greatest achievements of our asso is "CHARITY HANDS". Once one of our classmate was in need of collecting money for one Child's (Ear) operation, that time we collected money. But we couldn't reach sufficient money. And also another friend was in need of collecting money for an orphanage. In such situations we were unable to help soon. So we decided to collect some money from friends whenever possible and save then to use whenever in need. Now this also most welcomed by our friends and has been running successfully.

I hearty thanks to my classmates who encourage me and giving their constant supports.

The most thankful members by whom I started this association are..

1.Karthikeyan
2.Joshua Samuel
they only often asked of about assignments...
