One strategy folks can use is, if someone does something in the present tense, then just piggyback off what they did and assume you are there OR set the first sentence up as if you are playing off their action. Let me show you what I mean:
Example 1: "Perry offers to help go to the castle and bring down the elf kids."
Example 2: "Perry goes to the castle and brings down the elf kids with the aid of the others."
Now, which of these two is easier to piggyback off of? Let's pretend I'm Lia now and I'm trying to post after Perry in the timeline.
Example 1: Nothing has happened so my post goes, "I will help with the children." Or some other generic post that doesn't help move things along because, again, no action is there to play off of.
Example 2: "After arriving to the castle with Perry and the others, Lia pulls a child aside and says.... Before helping to bring them down to the elf encampment."
See how example two flows better because it's happening in the present versus some hypothetical future scenario? It's just a lot easier to play that way when people act rather than say they ready an action.EDIT:
Lawrance, the reason I brought this up in the first place was because you were just complaining about this exact problem just a second ago. Because no one ever said, "I call up Lawrance and tell him to prepare the kids and the egg," people kept posting in the future tense so that the message never reached Lawrance which meant you couldn't really post without making it really awkward or making assumptions. Basically, I agreed with you.
