Syntax corr.

l. 14: I've inserted the missing commas ("um-zu"-construction);
l. 35+36: I've changed the preposition (analogy plus phrasal term)
Term discussion

(Line 4)I wanted to discuss with you alternative terms for "wall". I'd consider terms like e.g. "pinboard", "bulletin board" or maybe "notice board" more appropriate. Terms including a wall would suggest the concrete material used for the board and that's not the way this pinboard is used or seen in WBB. Thus, what you think about renaming that feature?
