Think Tanks are similar to General Assemblies in the way that they are a way for members to meet with the board and discuss, debate, and propose ideas and advice for the future of SES. 

However, the key difference is that Think Tanks are on a much more informal setting and no voting procedures are held during Think Tanks, they're strictly meant for discussion and problem solving. 

The Board usually organises three Think Thanks throughout the year, although, unlike General Assemblies, there is no fixed amount of Think Tanks that must be held so it is up to the Board's discretion whether to hold more or less Think Tanks.
