Most conferences/meetings/workshops offer some kind of financial aid to attend. This may include registration fees, travel costs, and/or lodging. Often you can volunteer to get these costs covered. If you can't or don't want to volunteer you can often apply for funding. Funding may or may not be tied to presenting a talk or poster. These types of grants are commonly underutilized, especially within our section.
