Pronunciation
How many tones are there? What does the … tone do?
There are four tones, but each one has various uses depending on the part of speech they are used with. Simplifying things a lot, 
is for particles and verbs, 
is for particles and (pro)nouns, 
marks subordination, and 
is for adverbs. See Tone for a thorough overview.

What's up with the letter q in this language? Pronunciation of q
q is somewhat special and its pronunciation may not be immediately obvious. It is pronounced like English ⟨ng⟩ (IPA [ŋ]). The use of the letter Q is a nod to Rex May’s Ceqli, an international auxiliary language with loglang elements; it’s also found in natural languages such as Fijian (where it represents [ᵑɡ], to be exact).
Writing
How do I type the tone marks/symbols/diacritics?
Please see Input methods.
What's with the ı / i without dot / dotless i?
Writing ı without the dot distinguishes it more from an i that carries a tone mark, it also makes more room for an adjacent tone mark. Overall, it just makes things easier to read. See Latin writing system.
Grammar
Can I fill fewer slots than a verb has?
Probably! See Underfilling.
How do I skip slots? (What's the equivalent of Lojban's FA?)
Toaq intentionally doesn't have this feature. Just fill the slots with pronouns.
How does bọ work? What is the meaning / place structure of bọdo?
Semi-officially, it moves the direct object to the front, and removes the old subject. See bo-.
How do numbers work?
The official number system is that numbers are just verbs: saq means "___ are three in number", so Saq jío means "the buildings are three" and sá jıo saq means "some buildings that are three" (three buildings).
A more elaborate unofficial number system is described at User:Loekıa/Numbers.
