Here's another thought on posting while on vacation, why not save to draft. You still get to keep the data that you are wanting to enter, and you don't upset the applecart.
If categories are expecting a photograph, how would they know if a photograph is really going to follow? I have been reading a number of posts this evening about armchair waymarkers. Nothing would signal it more than if one posted 50 or 100 waymarks in the period of a couple weeks with no photos.
As for me, I am just waiting, or am posting on rainy days. I have been in Oklahoma for the past six weeks, doing nothing but compiling waymarks. I'll catch up eventually (this winter).
I have noticed BruceS post a number of items that are out of sequence. I wouldn't think he is flying from coast to coast, but just clearing the logs he has collected.
By the way, don't come to Oklahoma, until I get my Historic Districts posted... it is nearly impossible to get one in St. Louis (Haha).
