Obviously, speaking with more experienced members can give you much information, though you must be certain that their advice is backed by provenance (the member should not be offended by a request for documentation and should, in fact, have provided it before you asked). Obviously a preference should be made for advice from the AO, though hopefully any other information given you will not be contradicted!
Bibliographies and lists of recommended books can be helpful, but a list of books that should be avoided or not believed is often just as vital! Do not trust everything that anyone tells you or that reenforces your beliefs. Do not trust anyone who make a a statement and provides no provenance, and do not trust anyone who uses a discredited person as provenance.
Personal research is essential. Just remember that what you find may be with odds with old and cherished myths. Never be reluctant or hesitant to discard old beliefs when you uncovered documentation that contracts them! Please note that sagas were historical fiction that was written down several centuries later. They probably contain true parts, but using them as unassailable fact is similar to using “Prince Valiant” as unassailable fact. Stay away from Pinterest, Reddit, Wikipedia and similar sites unless you intend to do further research elsewhere!
Attending events is helpful. This will tell you whether reenacting is for you. You can talk with fellow members, observe interactions with MoPs and perhaps even have your own. Have fun and be friendly to both fellow participants and to MoPs, laugh a lot and offer to help where needed. Thank people who help you, and talk to MoPs. If you do not know the answer to a question, admit it and don’t feel bad about it. Refer the questioner to someone who does know the answer, and learn the answer yourself! And above all, remember that as a reenactor, you represent all reenactors!
The experience at an event may be very enlightening and, hopefully, enjoyable. And perhaps, after this experience, we may embrace you as another experienced fellow reenactor!
