Pro Basic (free) plan option
Included features: search by "Last name, First name, Place"; manual alerts from a search; unlimited family tree size; back-up family tree; sharing of public pictures and record archives; limited storage (250 MB) for personal photos and records; community forums.
Pro Very affordable premium plan
Premium plan is very low-cost, compared to most "major" genealogical and historical record sites. Cost is $12.50 for 3 months (avg. $4.17/month), and offers plenty of "perks". Definitely worth the premium plan pricing.
Con Most records paywalled
Very limited access to hosted collections without paying for the premium membership.
