It always seems so easy to make or design a logo for an event. Recently at Creativiti Project, we offered a link to a video on how poorly designed city flags are. Now, at ELT Rants, Reviews and Reflections, a friend of the blog author looks into TESOL conference logos. Ah, TESOL is an abbreviation of several forms of "Teaching English as a Second Language".
The open box logo for KOTESOL's International Conference was used as one (of several) example of 'the bad'.
I am speaking at the Jeju Regional KOTESOL Conference this Saturday. I don't see a logo at the link. Jeju KOTESOL does have a nice logo emphasizing the island and its tropical allure. It has no obvious symbol of English or teaching.
