I received a full MS request eight months ago today and received personal confirmation that it was received. This particular agent promises to respond to everyone, even when they are only querying. I'm concerned because I waited until the three month mark to politely nudge first then again at the six month mark, yet I never received a response either time.
I honestly don't know if there's anything I can do besides what you said about nudging every six to eight weeks. Like every writer, I'm hesitant to "annoy" the agent. Does eight months sound ridiculous in the realm of full MS submissions, or do I need to just suck it up and deal? Any help would be much appreciated.
Your question prompted me to look at my pending full requests.

1-4 are six to seven months old. I'm sorry to say that's actually the BEST it's been in almost a year as well.
Generally I try to answer nudging emails cause I understand that writers are on rodent wheels of anxiety during this process, but some agents can't stand to reply "sorry, not there yet" and so take the path of least reply and don't say anything.
I know this because when I've replied "hey, sorry, not there yet" it's all too common to get the reply "well, when WILL you get to it??" and the answer is "hell if I know." That's just not something you ever want to say to a writer, let alone in any kind of written format.
I will say that nudging every six to eight weeks feels pushy. I'd do more like 90 days.
Only you can decide when enough is enough.
I will tell you this: I've signed clients who waited more than a year for a reply. I've signed clients who've waited more than two years.
