hello

How can I start from the same place that I have reached ( befor logging out )

everytime I start from the city so I have to cross the same long raod ( to finish a qeust )?

Last one where to buy armors and wepeans ( I only met one who wants some thing in order to make armors ) ?

You can only start in a city. If you leave the city, and then log out, the location you will be at when you log back in is the last city you were in. Armor crafters are in a few cities, but it depends on what kind of armor you want and which game you are playing. Wiki has a list of each armor, where it is sold, what it looks like, and what is required to buy it. There are collectors who can trade armor for various items, which is possibly what you are referring to. Weapons also have crafters and collectors, but most people use weapons acquired from what monsters drop. If you need or want better weapons than you have, it is often faster to find a collector to get one, or trade with another player.

Not every town/outpost has an Armor NPC.

thank you for your help i`m reading the wiki I think I need more free time before playing

I`m now lvl 8 E/M Prophecies campaign where to start pvp?

There are 2 tutorial pvp arenas in Prophecies, one is in Ascalon City for lvl 1-10 chars and another is in Yak's Bend for lvl 1-15 chars. You enter the arena outpost by talking to the corresponding Arena Guard located Ascalon/Yak's.

But hold your breath, it's almost impossible to get into a match there, since nobody plays in these arenas. The real pvp takes place in the Battle Isles, which you enter either with a dedicated pvp character (immediately rolled as lvl 20) or with a lvl 20 pve character that has reached Lion's Arch or any other city with a port (Kamadan in Nightfall, Kaineng City in Factions).
